• Select the variable from the pull down ID data tree. This would normally be a counter incre-
ment value.
• The divisor is used to divide the counter increment. So use 10 to have an output of 50Hz for
500 increments per second.
• Select the maximum frequency of the output, from 50 to 2 Hz.
• Select the duty cycle from 25%, 50% or 75%. This means that e.g. 25% of the time the signal
will be raised, the other 75% it will be low. Typically 50% will be chosen.
• It is possible to reverse the logic (invert high and low) of each output by enabling the Invert
tick box.
